Description

Conveying belt device

Technical Field

The invention relates to the field of automatic transportation equipment, in particular to a conveyor belt device.

Background

In the 17 th century, the united states began using aerial cableways to transport bulk materials; in the middle of the 19 th century, various modern-structured belt conveyors have been developed in succession. In 1868, belt conveyor conveyors emerged in the uk; in 1887, screw conveyors appeared in the united states; in 1905, steel belt conveyors appeared in switzerland; in 1906, inertial conveyors appeared in uk and germany. After that, the conveyor belt is influenced by the technical progress of mechanical manufacturing, motors, chemical industry and metallurgical industry, is continuously perfect, gradually develops from the completion of the conveying inside a workshop to the completion of the material handling inside an enterprise, between enterprises and even between cities, and becomes an indispensable component part of the mechanization and automation of a material handling system.

Conveyor belts are generally classified according to the presence or absence of traction elements, conveyor belt installations with traction elements and conveyor belt installations without traction elements. Conveyor belts with traction elements generally comprise: the device comprises a traction piece, a bearing member, a driving device, a tensioning device, a direction changing device, a supporting piece and the like. The traction piece is used for transmitting traction force and can adopt a conveying belt, a traction chain or a steel wire rope; the bearing component is used for bearing materials and comprises a hopper, a bracket or a lifting appliance and the like; the driving device is used for powering the conveyor and generally comprises a motor, a reducer, a brake (a stopper) and the like; the tensioning device generally comprises a screw rod type and a hammer type, and can keep a certain tension and sag of the traction piece so as to ensure the normal operation of the conveyor belt; the supporting member is used for supporting the traction member or the bearing member, and can adopt a roller, a roller and the like. The structural characteristics of the conveyor belt equipment with the traction piece are as follows: the material to be conveyed is carried in a carrier member connected to the traction element or directly on the traction element (e.g. a conveyor belt) which is passed around rollers or sprockets and connected end to form a closed loop comprising a loaded branch for conveying the material and an unloaded branch for not conveying the material, the material being conveyed by the continuous movement of the traction element.

There are also conveyor belt devices on the market, for example the one of patent No. CN207726418U, which tension the conveyor belt by means of a weight, i.e. the two ends of the conveyor belt are not at the same height as the ground, one end is fixed at a higher position, and the other end slides downwards under the action of gravity through a slope, thus tensioning the conveyor belt, but this tension mode also has some disadvantages: firstly, it is only suitable for obliquely placed conveyor belts, because the tensioning effect is lost if the two rollers are placed horizontally, and at the same time it is not advantageous to adjust the tensioning of the conveyor belt, because it is tensioned by the effect of gravity, and if the gravity is insufficient, the conveyor belt cannot be tensioned completely, and a slip phenomenon may occur; also, for example, CN207450911U, is a longitudinal and transverse belt conveyor, which can transport in both transverse and longitudinal directions, but the whole belt conveyor rotates during reversing, so that the equipment occupies a large space, and the base is well defined so that it has no adjustment capability, and the equipment is horizontally placed and is only suitable for use in the horizontal direction.
